7 ATTACHMENT Fort Moron EXHAUSTSJ A piicanba filed September.

J This einvention arelates to attachments{for escaping from the e zihaust pipes will cause the'device to sound and even an ordinary layman cantell by the sound whether or not the engine is operating properly, and also to determine to a great extent just what is wrong with the engine.

A further object is to provide a device of this character whichcan be manufactured and sold at an extremely low price, which will be strong and durable in use, and which, will most efliciently perform the functions for which it is intended. v

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts which will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings Figure 1 is a view in side elevation, showing my improved device attached to the end of an exhaust pipe; I

Figure 2 is an end elevation of Figure l; Figure'3 is a broken top plan view of Figure 1; V

Figure 45 is a view of the vibrator detached; I Figure- 5 is which is bent vibrator.

1 represents the exhaust pipe of an internal combustion engine. On this pipe I secure'my improved device which includes a clamp having an arm 3 thereon that extends downwardly from the lower portion of the clamp and then. upwardlyand rearwardly, forming a supporting bar 4.

a broken view, of the. blank to form the support for the 'To this supporting bar l I connect my improved vibrator 5, which may be of any desired size and shape, and of metal or any [other suitable material. This vibrator is normally spaced from the supporting bar 4 and has a depending integral tongue 6 which is secured to the bar at by rivets 7 or other suitable attaching means.

The vibrator is free to bend along the tongue 6 and may move toward and away from the supporting bar as indicated by the dotted line positio-nsin Figure 1.. The ex- 13,.1927, *Serial No; 2191360.

make a sound, and the earof the eigperienced onerator can detect byjthe sound de fects in t 1e operation the motor."

' I have illustrated a particular construchaust from the engine blowing against the vibrator causes the ,latterlto Qvibrate and tion' which shows the clamp 2 with the arm 3 and bar 4, all constituting a single in tegral sheet metal, blank which is bent into the desired shape; The parts 23v and 4 are disposed at right angles to thepart 2, and said part '2 is bent so as to fit around the exhaust pipe and has perforations 8 in its ends to receive a screw 9 andwing nut 10 to clamp the same around the exhaustpipe.

It is perfectly obvious that the device may be'made in various ways and include any desired number of parts but'in any event I employ asupporting member connectedto the exhaust pipe, and a vibrator connected to the support and mounted so asto freely vibrate or create a sound or noise due to the gases.

It is to be understood of: course that the particular sound will depend upon the operation of the engine. In other words, if the engine is operating perfectly, the vibrator will make .regular sounds, and, if the engine is operating. imperfectly, it will make irregular sounds, and the difierences in the sounds will give the operator knowledge as to the working of the engine.

To prevent any possibility of the vibrator being drawn by suction against the end of the exhaust pipe, I extend the clamp'beyond the end of the exhaust pipe and provide openings 11in the projecting portion of the clamp.

While I have illustrated what I believe he a preferred embodiment of my invention, it is obvious that various changes and alterations might be made in the general form of.

the parts described without departing from tively connected to the clamp and located in the path of the exhaust gases from the'exhaust pipe.

' 2. A device of the character described, in-, a

eluding means for attachment toan exhaust pipe of an nternal combustion engine, a depending arm on said means, an" upwardly pr ectmg bar integralwvith the arm, and a vibrator secured to the bar but movable relative thereto and said vibrator located in the path of the exhaust gases.

3. A device of the character described, in-

cluding means for attachment to an exhaust plpe of an internal combustlon eng ne, a -de-'* pending arm on said means, an upwardly projecting bar integral with thearm, a vibrator, and a tongue on the vibrator fixed to the bar and resilientlybendable so as to permit the vibrator to move toward and away fromthe bar and said Vibrator located in 4. As an article of manufacture, a device adapted to beconnected to the exhaust of an internal combustion engine and a vibrator connected to the device and caused to sound by theescape of gases from the exhaust and said vibrator located in the path of the 'exhaust gases;
